Electrostatic atomization device

Abstract

An electrostatic atomization device that prevents the cooling capability from being lowered due to contact of an atomization electrode with another ember, while effectively preventing surplus production of condensed water that would destabilize discharging at the distal end of the atomization electrode. the electrostatic atomization device includes an atomization electrode having a cylindrical electrode body and a base which is informed at a basal end of the electrode body and has a larger diameter than the electrode from the base to produce condensed water on the atomization electrode. Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode. The partition plate and the base of the atomization electrode form a water collection region in between.
